Application led November 28,/1927.` Serial No. 236,027.:

f This linvention relates to shoes forathletes 4 or others .following the Various sports rand which shoes are designed to prevent the perf son wearing them fromL slipping on the surface over which they yare traveling. Such shoes are usually provided with projecting studs or whatfis yknown as cleats secured to the sole andheel portions of the shoe. It is common able. sok that they may` be renewed when broken or worn and the object'of the present invention is to providean attachment ywhich ris such as to preclude the possibility of the fastening device being broken under the heavy strain kto which these cleats are ysubjected when in use. A further object is to so construct each cleat and its fastening device as to facilitate the removal and replacement of the cleat and also to prevent the body of the cleat from beingbroken away andfeX- posing its fastening means, leaving the fastening means in such a condition as to cause injury to the other players 4by reason of the exposed metal fastener being left projecting `from the shoe sole without being covered by the cleat. It is also an object to provide a strong and rigid metal core for the cleat upon which core ythe cleat is molded and very securely attached .thereto by the intimate engagement of the cleat body therewith. A #further Object of the present invention is to provide a cleat fastener so arranged as to firmly and securely clamp the same in place on the shoe sole and afterbeing clamped is securely locked against detachment, said fastening means including ak screw stud and a reinforcing member arranged to receive and hold the cleat and at the same time strengthen the screwstud. I

With the above and other ends in view, the invention consists in the matters hereinafter set forth and more particularly pointed out vin the appended claimsreferencebeing had to the accompanyingdrawingin which Figure 1 is an inverted plan view of a shoe showing cleats applied to the sole and heel portions thereof, with some of these Cleats ywhich embody the present invention shown in section and with portions removed to :more clearly disclose the construction;

practice to make these cleats detachi fdrawing is merely illustrative `of Fig. l is a sectional view similar to that of I 1 tFig. y2 and illustrating a modified construclon; n

kFig. 5 is a plan view of Fig. 6 is a sectional `detail illustrating the manner of attaching screw studs to the metal vsole plate, and y s F ig; 7 is an enlargedinverted end elevaf vtion of the screw stud shown in Fig. 6.

The shoe shown fin the accompanying a form of to which, the cleats embodying the shoe - present invention may be attached, this shoe ybeing of any well known construction and having an outsole 1 and insole 2 and a heel 3., As these cleats may be appliedto either the ,solek Or heel orboth, and applied in the same manner tok each part, their application to the shoe is illustrated in detail by shoW- 'ing the same in the detailsk as applied to the .sole of the shoe. y s

Referring more particularly to Figs. 2 and 3, the cleats Llare preferably formed from hard rubber or other materialwhich may be molded or cast into the desired form, the body of the cleat being preferably of truncated conical formation and embedded within each cleat body is a ymetal core 5 in the form of a thimble or tubular member having a closedkinner end and provided with eX- ternal annular grooves 6 so that when ythis n corey or thimble is set within the mold in which the cleat body isformed, the material of thebody will flow intothe grooves 6 and be rmly united with the core to preclude the possibility of the cleat body from being split or Aturned awayy from the thimble in use.

To securely and detachably attach yeach cleaty to the sole kof the shoe, the screw threaded stud 7 is yprovided and this stud is forced through an opening in the inner and outer soles ofthe shoe with a flathead 8 on the stud embedded within the inner sole 2. Ribs 9 on the stud beneath its head 8 are provided for the purpose of prevent- F 2 iis.y any enlarged longitudinal :section ,substantially upon the line 2-2 of Fig. l;

smeared@ piste;

ing the rotation of the stud after it has been forced through the sole with its head and they ribs 9 firmly embedded in the shoe sole.

The stud 7 is further securely held in placek by a clamping and reinforcing `member 10 which comprises an internally and externally screwthreaded sleeve 11 having a base flange 12 and an opening 13 in this flange. This clamping member 1() is screwed upon the stud 7 after the stud has been passed through the shoe sole and is turned down hard against the outer surface of the sole with its flange 12 in rm contact therewith. The stud is therefore firmly clamped in place and they sole compressed between the'head 8 of the stud and the flangeV 12 of the clamping member. After the stud has been so secured kin placeby the clamping member 10, said member is firmly and securely locked against rotation upon the stud 7 by means of a nail or other fastening member 14 which is driven into the ysole through the opening 13 in the flange of the locking member, 10.

-The core or thimble is internally screwthreaded toreceive the externally screwt-hreaded sleeve of the clamping member and the base ofthe-cleat 4 is recessed as at 15 to receive the fiange 12 of the clamping member when the cleat is screwed into place upon said sleeve of said clamping member, and therefore the annular edge portion of the base of the cleat will come into firm engagement with the surface of the shoe sole outside of the flange 12 and have a rm bearing thereon to prevent any lateral movement under strain when the shoe is inu'se.

By providing the'clamping member with ra sleeve portion to screwupon the stud`7,

this clamping member not only holds the screw firmly in place and clamped to the sole of the shoe but also forms a reinforcement for the projecting portion of the screw stud, and by externally screwthreading this reinforcing sleeve 11, the met-al corel of the cleat may be readily screwed thereon and the memberl 10 then forms a stud of large diameter for the detachable engagement of the cleat therewith.

lt hasbeen found that where cleats of this character are secured in place by means of a single screwthreaded stud or bolt that this stud is very liable to bebroken off at the base of the cleat under the heavy strains to which the cleatis subjected, the stud being weakened at this point by its external screw thread, but in the present construction the sleeve 11 forms the stud upon which the cleat is mounted vand as this sleeve is provided with a base flange in firm contact with the outer surface of the shoe sole, it forms a very strong and rigid reinforcement for the screw stud and as the metal core or thimble of the cleat is screwed upon the sleeve 11 into rm contact with' the flange 12, there is no chance for play or lateral movement of ydirt and dampnessy and with `the the cleat which would put a heavy strain upon the comparatively small screw stud 7 and tend to break it olf.

In the ordinary construction, when one of these'screw studs breaksoff within the cleat, it is very difficult to remove the broken portion of the stud from the cleat and it is therefore necessary to throw the cleat away and provide a new one and also to remove the portion of the stud from the shoe sole and put another in its place. In the present construction, the removal of the cleat when it becomes'worn is an easy matter because of thev clamping member 10 being screwed into the socket or thimble ofthe cleat with this thimble entirely closed'to exclude the thimble seated upon the flange of the'clamping member. 'lhen the body of the cleat becomes worn away in use, it matter to unscrew'it from the sleeve 11 and screw another in place thereon. Further the core or thimble which is embedded within the body of the cleat 4 is of sufficient diameter to afford a very strongv and rigid reinforcement for the body of the cleatl and therefore the liability of the' cleat body becoming broken away. in useand exposing the metal core is obviated and should the bodybecome worn awayk in use, the comparatively smooth and rounded outer end of thecore only will be exposed and injury to other players will be reduced "to the minimum. v

To provide a firmer and more rigid base or place of attachment for the screw stud to the shoe sole, it may be found desirable, particularlyin the more expensive shoes, to insert between theinsole 2 and the outer sole 1 a thin sheet metal sole plate 16 having elongated openings 17 therein placed in the positions in V'which itis desired to attach the several cleats 4. When such a sole plate is used, the screw stud 18 is inserted through one of the openings 17 and through asuitable hole provided in the, outer sole of the shoe, with the head 19 of the stud incontact with the inner surface of the plate and beneath the insole 2. The stud 18, directly beneath the head 19 isformed with an elongated neck portion to fit within the elongated opening 17 in the plate 16l and thus prevent rotation of the stud, and adjacent this portion 20 is an annular groove 21 formed in the'neck portion ofthe stud between the elongated portion 20 and a conical portion 22. Afterthe stud has been inserted in the opening in the sole plate, a collar or ring 23 which is of a very close lit over the portion 22 of the neck of the stud and this collar is forced on to the neck and over the groove 21 so that it will spring into the groove slightlyk and thus the stud will be firmly clamped in place within the opening in the sole plate.

is therefore a simple In the construction where a sole plate is used, the stud 18 may and preferably is of 'a larger diameter at its screw-threaded outer end, and as it is very firmly and rigidly supported by the sole plate, it becomes unnecessary to reinforce the outer screwthreaded end of this stud by means of a reinforcing member and therefore the outer endof the stud is screwed directly into the core or thimble 5 of the cleat 4.

Obviously other changes in the construction and arrangement of parts may be made within the scope of the appended claims without departing from the spirit of the in vention and I do not limit myself to the parv ticular construction shown.

Having thus fully described my invention what I claim is:

l. In combination with a shoe having a sole portion provided with an opening therethrough, a screwthreaded stud to project through the opening and having a head to engage the inner part of the shoe sole, a tubular reinforcing member having an internal screw thread to engage the outer end of the screw stud and firmly clamp the sole portion of the shoe between said head and reinforcing member, means for preventing rotation of said stud within the shoe sole and a n cleat screwed upon the outwardly projecting tubular reinforcing member.

2. In a shoe having a sole portion provided with an opening, a screwthreaded stud eX- tending through said opening and having a head on its inner end, a tubular reinforcing member having an outwardly extending flange at one end and screwed upon the outer end of said stud to firmly clamp the sole portion of the shoe between the head on the stud and the flange on the reinforcing member, means for securing the reinforcing member to the shoe sole to prevent rotation of the reinforcing member on the stud, and a cleat detachably engaged with the outwardly projecting portion of the reinforcing member and having a recess in its base to receive the ange on the reinforcing member.

3. The combinationwith a shoe having a sole portion provided with an opening, of a cleat comprising a body and a hollow metal core extending within said body' from the base thereof and internally screwthreaded, a screwthreaded stud extending through the opening in the shoe sole, a reinforcing tubular member internally screwthreaded to engage the outer end portion of the stud and externally screwthreaded to screw into said core.

In testimony whereof I aiiX my signature.
